Carriage Bolts 603


Metric & Multistandard Components Corp. carries DIN 603 Carriage Bolts in Property Classes 4.6 and 8.8, and A2 Stainless Steel.

Carriage Bolts are threaded fasteners with a round head and a square neck immediately beneath the head. The Square neck will keep the Carriage Bolt from turning as a nut is tightened or loosened.

Carriage Bolts are suitable for attaching a fixture to wood where a round hole the same diameter of the bolt has been drilled through the wood. As a nut is tightened on the bolt the square neck is pulled into the hole which will keep the carriage bolt from turning.Carriage bolts can also be used on metal parts where a square hole has been made that will accept the square neck of the bolt and hold it in place.

Since Carriage bolts do not have a drive feature they are really only suitable to use hold together items with the use a separate nuts.
